Short answer: To apply for a Texas Master Electrician license you need two things: a Journeyman Electrician license held for at least two years, and 12,000 hours of on-the-job training under Texas Masters, verified by each one. Your earliest potential application date is the later of your two-year Journeyman license anniversary and the date you accumulate 12,000 qualifying supervised hours. TDLR must still review and approve your application and experience, and you must pass both portions of the licensing exam.
The exam is the part you can practice for. The Texas Master Practice Pack has 368 practice questions and 10 timed two-part mocks with the published PSI exam lengths: 75 NEC Knowledge questions in 150 minutes and 33 Calculations questions in 170 minutes. All 110 calculation questions have step-by-step solutions. The 10 mocks draw on the bank of 368 practice questions. US$79 once.

The gates to Master
| Gate | What TDLR asks for |
|---|---|
| Journeyman tenure | You have held a Journeyman Electrician license for at least two years. Journeyman Industrial Electrician experience does not qualify. |
| Supervised hours | 12,000 hours of on-the-job training under the supervision of a Master Electrician licensed in Texas, verified by each supervising Master on an Experience Verification Form |
| Application | By mail, with a $45 non-refundable fee |
| Exam | Two parts, 70% or better on each |
Sources: TDLR Master application page. TDLR’s FAQ adds that the two-year Journeyman requirement comes from Texas Occupations Code §1305.153 and that a Journeyman Industrial license does not meet it (TDLR electrician FAQ).
If you held a municipal or regional Master license, TDLR says you may verify your own on-the-job training for the years you held it.
Do your apprentice hours count toward 12,000?
TDLR’s Master page asks for 12,000 hours of on-the-job training under the supervision of a Texas Master. It does not say the hours must come after your Journeyman license, and it lists the two years as a separate requirement. TDLR lists the 12,000 hours as a separate requirement from the two-year Journeyman tenure. Keep documentation for all of your supervised hours, and confirm any unusual history with TDLR before you count on it.
Two cautions. First, every hour still needs a supervising Master to verify it, so the record-keeping habits from your apprentice years still matter. Second, if your history is unusual, for example out-of-state work or long gaps, ask TDLR before you count on the hours.
Worked examples: your earliest Master date
A planning estimate, not an official TDLR determination:
- Tenure date = the date your Journeyman license was issued + 2 years
- Estimated hours-completion date = use the date you expect to begin or continue qualifying supervised work as your starting point. Subtract your documented qualifying hours from 12,000, then divide the remaining hours by your expected annual qualifying work hours. This is a planning estimate, not a TDLR eligibility determination. Account for breaks in employment, changes in working hours, and any experience TDLR may not accept. If you already have 12,000 qualifying hours, the hours gate may already be met, subject to TDLR verification
- Estimated earliest eligibility date = the later of the two dates, assuming both requirements are satisfied and the supporting experience is accepted by TDLR
Example A: full-time, tenure is the last gate
Journeyman license issued November 1, 2026, with 8,300 verified hours. Works about 2,000 hours a year.
- Tenure date: November 1, 2028.
- Hours still needed: 12,000 − 8,300 = 3,700.
- Time: 3,700 ÷ 2,000 = 1.85 years, or 1.85 × 12 = 22.2 months. That lands in early September 2028.
- Earliest date: November 1, 2028, because tenure comes later than the hours.
Example B: part-time, hours are the last gate
Journeyman license issued November 1, 2026, with 8,000 verified hours. Works about 1,200 hours a year.
- Tenure date: November 1, 2028.
- Hours still needed: 12,000 − 8,000 = 4,000.
- Time: 4,000 ÷ 1,200 = 3.33 years, or 40 months. November 1, 2026 plus 40 months is March 1, 2030.
- Earliest date: about March 2030, because the hours come later than the tenure.
Example C: lots of overtime before Journeyman
Journeyman license issued November 1, 2026, with 10,400 verified hours. Works about 2,400 hours a year.
- Hours still needed: 12,000 − 10,400 = 1,600.
- Time: 1,600 ÷ 2,400 = 0.67 years, or 8 months, so July 2027.
- Earliest date: still November 1, 2028. Overtime cannot shorten the two-year tenure.
Check on Example B: 40 months × 100 hours a month (1,200 ÷ 12) = 4,000 hours, which matches step 2.

The 2026 NEC in print
NFPA 70, National Electrical Code (NEC) 2026, softbound. Texas adopted the 2026 NEC as the state electrical code effective September 1, 2026 (TDLR adoption notice). A print copy lets you check any section number yourself.
The Master exam
| Part | Items | Time | Pass mark |
|---|---|---|---|
| NEC Knowledge | 75 (5 not scored) | 150 minutes | 70% |
| Calculations | 33 (3 not scored) | 170 minutes | 70% |
From the PSI Candidate Information Bulletin for TDLR (updated September 15, 2026). The fee is $78 for both parts, and a retake costs $78. Since September 1, 2026, the exam is referenced to the 2026 NEC, and it is open book with your own soft-bound copy.
The Master exam is not a formality. In TDLR’s fiscal year 2025 statistics, 19.08% of Master Calculations attempts and 22.21% of Master NEC attempts passed (TDLR FY2025 exam statistics).
How to use the two years
- Renew on time every year. Four hours of CE and $30 each year keep the Journeyman license current. We found no TDLR guidance on whether a lapse interrupts the two years; if your license has lapsed, ask TDLR. See our Journeyman renewal guide.
- Keep collecting verification. Get an Experience Verification Form from each supervising Master as you go, using the same form as your Journeyman application (TDLR form ELC017).
- Start the exam work early. The Calculations part gives 170 minutes for 33 questions on services, feeders, motors and transformers, so speed comes from practice, not from reading.
- Mail a complete application with the $45 fee once both gates are behind you. The exam approval follows TDLR’s review.
Mistakes that delay Master applications
- Counting years on a Journeyman Industrial license toward the two-year tenure.
- Missing verification from a Master you worked under years ago.
- Assuming overtime shortens the two years. It only speeds up the hours.
- Studying from outdated NEC references. The City of Denison’s published summary identifies Article 120 as the 2026 location for branch-circuit, feeder, and service load calculations previously covered in Article 220. Confirm the applicable provisions in your own 2026 NEC before relying on an older reference (City of Denison 2026 NEC summary).
Before taking on business responsibility as a Master
Keep your personal Master application, a business-structure decision, tax registration, and contractor authority in separate records. An entity filing or an EIN alone does not establish electrical contractor licensing. The existing Texas business setup checklist covers formation, EIN, sales tax permit questions, and record locations. Use it for that preparation rather than treating an exam practice purchase as business approval.
Compare company structures and keep federal and Texas tax questions separate
Our business setup checklist summarizes the Texas Secretary of State business-structure guide: a sole proprietorship differs from a Texas LLC or corporation formed by filing a certificate of formation, and S corporation status is a federal tax election rather than a separate Texas entity form. That distinction starts the comparison; it does not tell you which structure produces a lower tax bill.
Use the following as a comparison worksheet for a CPA and, for legal responsibilities, a Texas attorney. Federal filing treatment, Texas tax applicability, current thresholds, rates, election deadlines, and your reserve amount remain UNKNOWN here. Record a dated answer for the actual owners and planned activity, using current official sources, before choosing a structure.
| Structure or election | Federal tax comparison | Texas tax comparison |
|---|---|---|
| Sole proprietorship | Confirm how the owner’s actual income, expenses, and any self-employment obligations would be reported. Applicable forms and amounts: UNKNOWN. | Confirm which state registrations, reports, or taxes apply to this owner and activity. Sales tax permit applicability and amounts: UNKNOWN. |
| LLC | Record the proposed owners and ask which federal tax treatment and any election apply. Do not infer that treatment from the letters LLC. Treatment and amounts: UNKNOWN. | Keep the formation record separate from the state tax review. Ask which franchise tax reporting and sales tax questions apply. Obligations and amounts: UNKNOWN. |
| Corporation | Ask how the proposed corporation and payments to its owners would be treated, and what records or elections need review. Treatment and amounts: UNKNOWN. | Ask which state tax reports, registrations, and payments apply to the proposed business and sales. Obligations and amounts: UNKNOWN. |
| Possible S corporation election | Ask whether the business is eligible, what an election would change, and what filing and payroll questions follow. Eligibility, deadline, and savings: UNKNOWN. | Ask what the federal election changes, if anything, in the separate Texas review. Do not copy a federal conclusion into the Texas column. Effect: UNKNOWN. |
For each option, note the owners, management plan, expected kinds of receipts, possible employees, and the records the adviser requests. Keep the federal EIN question separate from a Texas sales tax permit question. The IRS EIN page and Texas Comptroller permit page are the existing checklist’s starting sources; neither link settles the tax treatment of a particular electrical contract.
Completion evidence for this comparison: a private record with one row per option, separate federal and Texas answers, the source and date for each answer, the reviewer, and any unanswered question. A blank answer stays UNKNOWN. A completed learning worksheet is not an accepted filing or a tax calculation. This article does not choose an entity, calculate tax, or provide a paid tax or legal review service.
Review insurance, contract responsibility, and proposed changes together
The existing Texas job terms, tax records, and side-work guide separates contracting identity, scope, change approval, responsibility, and insurance evidence. Its official-source list is dated October 27, 2026. The TDLR Electrical Contractor application page is its licensing reference. Use the review questions below to prepare an evidence packet for the contract owner, Texas attorney, and insurance broker.
- Insurance: identify the named business, policy or certificate reference, relevant period, proposed activity, and broker contact. Ask the broker which documents and coverage questions need review for this exact work. Keep required limits, exclusions, any bond question, and actual coverage unresolved until the responsible reviewer confirms them; this checklist supplies no current limit or coverage decision.
- Contract: locate the controlling agreement and version. Record the parties, scope, exclusions, deliverables, and the people responsible for supervision, permits, inspections, purchasing, and customer communication. Ask the contract owner to resolve missing or conflicting terms before relying on them.
- Risk transfer: point the attorney to the exact clauses that appear to assign a duty, cost, loss, or responsibility to another party. Record which party and activity each question concerns. Ask what obligation is being proposed and ask the broker separately about its relationship to insurance. Do not mark a responsibility as transferred, a clause as enforceable, or a loss as covered from a certificate or a checked box.
- Change control: keep the current scope and the proposed change as separate versions. Record the request, date, source document, possible scope, price, schedule, and responsibility questions, and who may request, price, approve, and release the change. Preserve the written decision and its version. A request or discussion does not complete this review.
Keep a private review register
For each tax, policy, contract, responsibility, or change question, record: the document identity and version; source location; date checked; exact unanswered question; responsible reviewer; next action; and status. Add the answer, decision date, and supporting record only after the responsible person responds. Use UNKNOWN, pending review, or confirmed for a specific question rather than one general “approved” label.
Fictional example: A future shop is comparing a sole proprietorship and an LLC. Both tax columns remain UNKNOWN. A proposed work order adds a room, but the scope version and approval contact are unresolved. The learner records a CPA question about each structure, an attorney question about the responsibility clause, a broker question about the proposed activity, and a request to the contract owner for the current scope and change decision. No reviewer reply, tax outcome, coverage, or project result is assumed.
Stop and ask: If the party, scope, reviewer, approval, or coverage evidence conflicts or is missing, keep the item unresolved and seek the responsible professional’s answer before relying on it. This is a document review exercise, with no electrical work instructions. It does not authorize electrical work, establish supervision, interpret a policy or contract, or replace the authority’s licensing decision.
What you keep: your own private notes and document index. This article provides no online form, automatic saving, export, download, professional sign-off, or submission. Do not enter tax IDs, bank details, personal records, customer contracts, or policy documents into a learning exercise. A practice score, purchase, membership, or private completion record is separate from a professional review and from a license issued by the authority.
